FIBER-CLEANING MACBIN To -alf-l whom it may concern;

Be it known that I, ALrnEUs W. MONTGOMERY, a

i citizen of the United States, and a resident of New v ing forward the bai'k 5 to be treated. In line with the York city, borough of Queens, New York, have invented certain new and useful Improvements in Fiber- Cleaning Machines, of which the following is a specification. i

, Thel object of my invention is to provide a machine into which the bark r skin of the tree is to .be fed'a'ndv by which the pulpy or watery substance will -be quickly scrapedirom the bark or fibers whereby economy in the production of Manila hemp fibers may be effected.

' My invention comprises the novel details of improve-` setgforth and embodying myinvention, Fig. 2 is a.plan view of'part thereof, Fig. 3 is Van enlarged vdetail sectional view through the Scrapers, fFig. 4 is a cross section, enlarged, substantially on the line 4, 4, in Fig. 3, Fig. 5 is a plan view of Fig. 4, Fig. 'is a detail view of one of the dogs used with the chains for the scraper, Fig.` 7 is a detail perspective view of one of the scrapers and its dog', Fig; 8 isa detail view of the guide for the scrapers, Fig. 9v is a detail view partly in section ontheline 9, 9, in

Fig. 3, andV Fig.' 10 is an enlarged perspective view of thefinishingroller shown at the right hand side of Fig. 1.

Similar numerals of reference indicate corresponding parts in the several views.

In the drawings the numeral 1 indicates a suitable l frame in which are journaledfeeding rollers 2, `3, the roller 2 preferably being permitted vertical adjustment 'by means of screws 4 in -usual manner. `Said rollers are shown corrugatedvfor the purpose of engaging and feed-k rollers 2, 3, are movable blades 6 adapted to engage the pulp or pulpy substance upon lthe' inner side of the.r

bark to scrape the same from the bark, which blades are respectively opposed to movable slats or bars'7. The blades 6 lare carried by endless chains or the like 8, which pass over sprockets 9, 10,-suitably journaled upon frame 1, and the bars or slats 7 are correspondingly carried `by endless chains 11 passing over sprockets v12, 13 journaled in frame 1. In the enlarged'V view in Fig. 3 part-of Vthe chains 8 andV 11 -are broken away for the purpose of clearer illustration. The rela'- tive arrangement of the blades 6 and bars or slats 7 is such that a blade vwill aline with and substantially bear `on a bar or slatl so that Athey will travel at equal speeds thereby grippingthe bark betweenthem, as shown in Figs. 1 and 3. The relativerate of travel offthe blades 6 and bars or slats 7 with respect to the' surface speed of the rollers 2, 3, is suchtliat the blades and bars will travel faster than the bark is' iced-by the rollen 2,;3, vso as Specication of 'Letters restent.

The barsors'lats 7 areprovidedwitlildogsfand'f'a guide 7.1 similar to those above described, and 4the bars orslats 7 may be secured upon or made integral with cross bars 7Il swiveled in the links 11 and provided with dogs 16 engaging a guide 17, (see Fig, 9) serving to assure :ahorizontal position of the upper surfaces of the `slats beneath the `blades. yOnly partotl the dogs andjguides 16 and 17 are shown in Figs. 1 and 3.' for the sake of clearness. t Thesprockets 9 and 12 are geared together'so that they will travel at the saine surface speed to assure that the blades 6 andthe bars or slats 7 have the same rateof travel, and in thearrangement shown the rollers 2, 3 are driven at a slower speed than thespeed of the Vblades and slats. For thesepurposes I have shown a driving `pulley 19 connectedwith shaft 9' oisprocket 9, and having a Agear 20 vthat meshes with a` gear 21 connected with the shaft of sprocket 12, which by `the gears 2 2 23 connected'respectively withthe rollers. i l2 and 3. `0f course, ifpreferred, power Icould be zip-- vpliedv to any other shaft and transmitted in suitable manner to the chains and rollers.

.When the pulley 19' is driven in the direction `of the .arrow in Fig. 1 'and a strip of bark tobe treated is fed 105, `-means of reducing gearsand pinionso, `b, c operate i between the rollers 2, 3, the strip will pass between the knives 6 and bars or slats 7, and as they travel forwardly faster than the strip is fed by the rollers 2, 3

the lresult will be that the blades will scrape from the bark orkfiber the pulpy substance thereon. T-his pulpy substance 'maybe removed from the machinei by any' suitable means, as by allowing it to passup 'an' endless apron 24' supported and operated in well ,known manner, ,the fiber owing to its wet and flexible condition, 'droppingv down and following the bars f7" under-the adjacentend of apron 24, while the pulpy material that wouldaccumu'late'upon the fiberv is car- .A'sthereis some. space between the rollers 2, 3 and the.y working blade 6` nearestthereto therewill be some pulpy matter'let uponv the rear or unscraped end ofthe bark or fiberfat. the part then between said rollers landblades after the bark ,leaves the rol-1ers 2, 3, vand lwhile such-'pulpy Lmatter. may be removed rom the' strip-"or barkzb'y lhand in usual manner, I lprovide means for removing it -there'from'a'rs th strip ispassed through they machi'ne' 'llo this end I have shown an ,endlessapron 25 passing over-rolls 26 journaled in the mainframe, which rollsl and apron may'be operatedv by gearing 27, 28, 29, driven from the shaft of sprocket In line with the upper run of apron 25 is a table dr plate 30,-and `at 3l, 32 are rollers arranged similarly to rollers 2, 3, but driven at a greater surface speed 'than ythe speedfoi blades. 6, so as to assure that the fiber that has been acted upon; by the blades 6 will bel quickly delivered from 'the machine. l Above the ltable -is a-,drum33 having blades 34 to act on the pulpy sub'stance. at the rear endoffthe bark or fiber 5;y The drum4 33 is shown connectedfwith the roller 3l-by gearing 35, 36, 37, whereby the drum 33 will -be driven in the same direction-as roller 31, but at a surface `speed slowerv than the Arollers al1, 32. I havel shown the-shaft of sprocket 13 as provided lwith a lsprocket 38,' over which a chain39 passes to a sprocket 40 on the shaft of `roller3/2v (see Fig` 2), whereby the pull the bark/beneath said drum, but thtblardes o the latter will act upon the lpulpy matter volvtlre bark to strip it therefrom thereby nishing the clean"- A ing of the rear end of the strip of bark because as the rollers 3l, 32 pull'the bark faster than the travel of blades 34 the latter will scrape .the pulpy material,

,from the bark. By means of my improvements it will be apparent that by simply feeding the bark between the rollers:

2, 3, the pulpy material upon 'the bark will be quickly scraped therefrom and without injury to, the bark, whereby the operation o cleaning the bark is much quicker and more cheaply vperformed than by the usual hand method. c

Having now described my .invention what I claim'v -1. A- machine vof the character described comprising a l movable blade adapted to scrape pulpy material from bark, means for feeding bark to the blade, means for causing the blade to travel faster` along the bark than thel Alatter is fed under the blade, a rotary drum having blades to engage material on the bark, and means for drawing' the bark beneathsaid blades atl a speed greater tbantbe speed ofrotat-ion of said blades, substantially as described.

2. A machine of the character descrbedfcomprising a movable blade adaptedto scrape .material from bark, means for feeding bark rto the blade, means for causing is fed under the blade, a rotary drum provided 'with blades to engage the material on the bark not scraped off by the 'the blade to travel faster along the bark than the latter rst named blade, rollers to draw the bark beneath the l rotary blades, and means for operating said rollers at .a surface speed greater than the surface speed of rotation of said rotary drum, substantially as described.
